ARTICLE COVERED WITH SHEET PYROXYLIN Filed Aug. 5, 1923 wcyw PatentedSept. 22, 1931 UNETED STATES PATENT OFFICE HOWARD I. DE CORREVONT, OFCHICAGO, ILLINOIS,- ASSIGNOR TO THE BRUNSWICK-' BALKE-COLLENDER CO., OFCHICAGO, ILLINOIS, A CORPORATION OF DELAWARE ARTICLE COVERED WITH SHEETIPYROXYLIN Application filed August 6, 1928. Serial No. 297,904.

This invention relates to the covering with sheet pyroxylin, Or thelike, of articles having somewhat sharp edges, where it is desired tosecurely join the meeting edges of sheets of the covering material, atwhich edges the covering is naturally more liable to wear through thanat other parts of the surface of the article.

One object of the invention is to provide a core in an article of thetype described with an edge which is cut away in such a manner as toprovide space for a strip of pyroxylin for securing the exterior edgesof pyroxylin sheets constituting a covering for the core.

Another object of the invention is to pro vide an article coated withsheets of pyroxy lin of uniform thickness at substantially all pointsand having the edges thereof united by a strip of similar material.

A further object of the invention is to provide a seat of the typereferred to which is especially strong and durable.

Other objects and advantages will appear as the description proceeds.

Referring to' the accompanying drawings: Fig. 1 is a plan view of acloset seat embodying my invention;

Fig. 2 is a section of the same on the line IIII of Fig. 1, part of theseat being broken away; and

Figs. 3 and 4: areviews similar to Fig. 2

but illustrating modified forms of my in vention.

Although the drawings show the invention as embodied in a closet seat,this article was selected only as conveniently illustrating theinvention, as it may be embodied in other articles having somewhat sharpedges, such as the cover of a closet seat, a mirror frame, shelf,bathtub seat, or the like. It will be understood that my inventionapplies to the covering of any article having a somewhat sharp edge atwhich sheets of the covering are to be joined.

The core 1 of the closet seat has a somewhat sharp outer edge which isprovided with a recess 2 extending therealong throughout the entireperiphery of the seat. A strip of pyroxylin 3 extends along the edge andis reto dry.

ceived in and fills the recess. The bottom of the seat is fiat and iscovered with a sheet of pyroxylin i, and a similar sheet 5 covers thecurved top surface of the core and extends down over the strip 3 intoabutting relation with the sheet 4.

The core has also'a similar edge 6 extending around the opening in theseatand the jointof the pyroxylin sheets at the latter edge is similarto the one just described.

The improved coating is applied as follows The walls of the recess 2 arecoated with an adhesive and the strip 3 is then secured in position andthe adhesive is permitted The sheet 4 is then secured to the bottom ofthe core by an adhesive, which is permitted to dry, after which theouter edge of the sheet is trimmed off to bring it flush with the outersurfa'ceof the strip 3. The sheet 5 is then secured to the upper surfaceof the core by an adhesive and is brought down so as to abut against andextend beyond the sheet 4, after which it is trimmed off so as to'beflush with the surface of the latter sheet.

Pyroxylin coatings for articles are usually quite thin andhaveheretofore been of such character as to readily break and wear awayat sharp edges. The substantial thickness of the reinforcing strip 3 inthe improved joint eliminates this weakness and provides an especiallystrong and durableconstruction. The sheets 4 and 5, being ofsubstantially uniform thickness, have no weakened portions such as wouldresult from feathering, as has been done heretofore in making joints forpyroxylin sheets. Again, the

pyroxylin sheets are not bent angularly in such a manner as would causedanger of cracking, .and thus a defect of prior constructions has beenobviated.

Although the walls of the recess 2 have been shown as disposed angularlywith respect to each other, it is not necessary that they have thisshape, as the wall may be curved as shown at 7 in Fig. 2, or have otheforms if desired.

Again, the outer edge of the completed article may be trimmed off asshownat 8 in Fig.

4 to produce a more durable joint by removing the sharp corner.

With this construction it is not necessary to form the butt joint of thesheets 4 and 5 as shown in Fig. 2 with extreme care, as this joint istrimmed away as described leaving the edges of the pyroxylin sheetsspaced apart.

This construction has the further advantage that it may be used toenhance the appearance of the seat, as the reinforcing strip may begiven a different color from the coating and the contrast of the colorsis attractive to the eye.

The invention is not limited to the specific details of the embodimentsillustrated and described, but further modifications are contemplatedwithin the scope of the invention. For instance, the coating shown inFig. 4 may be composed of other substances than pyroxylin. If desired,hard rubber might be used instead of the pyroxylin sheets, thereinforcing strip being of a different color if desired.

A substantial range of equivalents is contemplated within the scope ofthe appended claims.

What I claim as new and desire to protect by Letters Patent is 1. In apyroXylin-covered article, the combination with a core having an edgeprovided with a recess, of sheets of pyroxylin coveringsaid core andmeeting at said edge, and a reinforcing stripof similar materialextending longitudinally of said edge and received in said recess, saidcore and sheets and reinforcing strip being united adhesively.

2. In a pyroxylin-covered article, the combination with a core havinganedge provided with a longitudinally extending recess, of a reinforcingstrip of pyroxylin extending along said edge and received in saidrecess, and sheets of pyroxylin of uniform thickness at substantiallyall points covering said core and said reinforcing strip, said core andsheets and reinforcing strip being united adhesively.

3. In a pyroxylin covered article having an exposed edge, thecombination of a core similar in shape to the article and recessed atone edge, a reinforcing strip of pyroxylin secured to the core Withinsaid recess, exposed faces of said strip being flush with adjacentsurfaces of the core, and sheets of pyroxylin adhesively secured to thecore and said strip. In testimony whereof I hereunto subscribe my name.
